What Makes Up the Name: mom + entrepreneur
If you really wanted to pitch a good movie, you could do one about a single, laid off digerati internet momtrepreneur who starts her own business while raising her toddler and makes a facebook app that finds her the man of her dreams and who was really the sperm donor for the baby she had because she was too busy working to find the man of her dreams! Hooof, that was a long sentence. Call me, Hollywood.
Origin: The earliest usage we could find was 2007, but who knows what bored stay-at-home mom thought it up before that.
